Product Highlights
Bending a 60-penny nail was a basic benchmark in the steel-bending tradition–but the strength of 60-penny nails varied all over the board, and there was no simple way to progress from easy to harder nails. Problem solved: since 1993, IronMind’s Bag of Nails has provided a graduated and standardized way to master this classic feat of strength: bending a 60-penny nail.
